The 17 pages that link to Speed, each with the reason it gives.
VelocityCompared with: Speed is the magnitude of velocity, but omits its directional information.
Kinetic energyRelated: Classical kinetic energy grows with the square of speed.
Arc lengthRelated: Integrating a parametrized curve's speed gives its length.
Uniform circular motionRelated: Uniform circular motion keeps this scalar quantity constant.
Scalar (physics)Compared with: Speed is scalar, while velocity includes the direction of motion.
KnotNarrower topic: A knot is one particular unit for measuring this rate.
Metre per secondNarrower topic: Metres per second can express speed without specifying direction.
Flow velocityCompared with: Speed gives flow velocity’s magnitude but omits its direction.
SpeedometerNarrower topic: A speedometer displays an estimate of this physical quantity.
Kilometres per hourNarrower topic: Kilometres per hour is one way to express this rate.
Miles per hourNarrower topic: Miles per hour is one specific unit for expressing speed.
Instantaneous velocityCompared with: Speed is the magnitude of instantaneous velocity.
